OK, went looking at the code. As far as I can tell, it would probably be
possible to teach the part of uclibc that does DNS lookups about the CD
bit. However, I'm not sure there's a way to pass the request for no
validation through the resolver to the right place; certainly not
without entirely reworking the way ntpd does hostname lookups (and
possibly other parts of the C library as well). Either way it's not
something I feel up to with the time I have available for hacking on
cerowrt. So I am abandoning this avenue of enquiry.

I'll be happy to work on improving the dnsmasq script with the
--dnssec-no-timecheck parameter approach; but if it is going to be
rejected in favour of a different approach I'd rather not waste any more
time on it... :)
